About

I am a Master of Science in Computer Science student at the University of Wisconsin–Madison, driven by a strong interest in full-stack and frontend development. Throughout 4 internships and multiple side projects, I’ve worked on building scalable systems and user-facing features across diverse domains. At 1111 Job Bank, I developed an internal configuration platform with Vue.js to simplify RabbitMQ integration for 20+ microservices, significantly improving operational workflows. During my time at Appier, I built and maintained image upload services handling over 100K+ daily uploads, and optimized CI/CD pipelines to accelerate deployment by 65%. At NTU’s Office of Academic Affairs, I designed a course allocation system that automated scheduling for more than 1M+ course-student combinations across the university. In addition to engineering, I enjoy combining product thinking, design, and business perspectives to craft solutions that directly address user needs. I aim to create intuitive, reliable products that drive meaningful value, particularly in technology-driven business environments.
